I'm new to the forum, and I love BMW but I am having an issue with my 84 633sci's automatic transmission. It is stuck in first gear, it will go into Park and it will go into reverse but it won't shift past first. I've changed the transmission fluid, the issue started when it was cold so I thought it might have been the fluid. I've looked on other sites and have found nothing, any information would be very appreciated. if you need any other information please ask.
